Hello,
Yes, please reference TIDA-01393 and PMP12004-HE for some performance reports that include ripple voltage.
Overall, the ripple is mainly a factor of the inductance, capacitance, layout, and (most importantly) the measuring technique.
Hi Teik,
Thanks for providing the update! Here is my feedback:
What is the purpose of having CTL4 connected to the S1201 switch? GPO3 is already driving CTL4 which will go high 5ms after CTL1 sequence PG. Can you disconnect CTL4 from the switch so…
Hi Layne, Thank you for your answer.
I have additional questions about Q3.
(Q3-1) I pull up each signal at +1.8V. Since the input voltage of the system is +12V, I want to generate this +1.8V from the LDOA1 (+3.3V) below via other external power IC. Is there…
The TIDA-01393 design uses the TPS6508641 device variant. Although we can independently review your schematic, this is the best resource that you can use to identify differences between your design and a known-good working design.
Hi JH,
1. My interpretation of those lines is that all of the other regulators on TPS6508640 were disabled and inactive. For the buck controllers the power required for the drive source was also accounted for in the efficiency measurements.
2. The only…
Hi Rachel,
I assuming this is a follow up from previous post: https://e2e.ti.com/support/power-management/f/196/t/919220
1. Correct.
2. The TPS6508641 is a pre-programmed TPS650861 with the settings for Xilinx. If you would like different settings, then…
Hi Kevin,
Thanks for your reply. Echo to your reply, please see customer feedback as below:
1. Customer plans to use an external LDO to supply for VPS_MGTRAVCC. But customer still wants to take advantage of VTT LDO. So they want to use VTT LDO(0.9V) to supply…
Hi Shyam Daram,
2. Page 37 of the datasheet lists the settings for the TPS6508641 OTP. There is no specific recommendation in the datasheet for that resistor setup, but it can be found in the schematic for the TIDA-01393 design I linked above. The resistor…
Part Number: TPS650864 Other Parts Discussed in Thread: TPS544C25 , CSD85301Q2 , CSD87331Q3D , CSD87381P , CSD87588N , CSD87350Q5D , TIDA-01393 Hi
The datasheet of TPS650864 shows some power map examples.
One of them looks like as below.
In this configuration…
Hi Jacek,
We have not publicly released any information about the internal resistor divider values in the past. These values can vary between 100k and 1M ohms and it will depend on specific settings for the device. These resistors are not trimmed to absolute…
